Buzz Aldrin salutes the first American flag erected on the Moon, July 21, 1969. The Lunar Flag Assembly (LFA) was a kit containing a flag of the United States designed to be planted by astronauts on the Moon during the Apollo program. Six such flag assemblies were planted on the Moon.
In order to figure out what size scope we need to see the flag on the Moon we have to know how big the flag actually is. For purposes of this analysis we will assume that the flag is 3 feet wide. We decided on using a flag width (dimension B in the diagram) of 3 feet (36 inches). Therefore A = 36/1.9 = 18.95 inches.
